142-182W single output isolated PCB mount DC-DC converters in a sealed metal half brick package. These isolated railway compliant DC-DC converters have a wide 4:1 input voltage range, adjustable output voltage and a high efficiency of up to 91% allowing full power operation without forced air cooling at 25°C. When used with a heatsink (stock number 706-6420) this temperature can be increased up to 60°C.
